Well, I tried something and it seems that I don't get freezings anymore when I choose the characters and a stage, but now the result screen gets black and freezes.
I removed the whole menu folder, extracted the sc_selcharacter.pac into the menu2 folder and deleted it from the common5.pac. Now I tried some matches, even with characters who caused trouble and 4 Pokemon Trainers with custom hacks, and it worked fine. Just when I go to the result screen, the image is black and nothing happens.
Can somebody try it, too (use Riivolution + Stage Expansion + cBliss)?
Maybe you should keep the menu folder, because the portraits inside are the ones for result screen...
Bah, that's a good idea to add him! And they said they will focus on the old characters... Who knows they could add? Please, no more Game and Watch!!!!
